I had some difficulty in commissioning an 8 ClaVal we installed on a 1500 gpm pump in Cranston a few years ago. We took out the inside test header and installed the SCV in its place an piped the suction line in ¼ soft copper. Joe from ClaVal had retired (too bad) but we managed to get a hold of a knowledgeable outside tech who helped us out. Seemed the preferred location was between the discharge and pump check (not after) and the sensing line be ½ right from the suction gauge tap (1/4) to the operator inlet (1/8). Once we changed that, it worked perfectly. Happy birthday GLC.

Im assuming it goes on the suction side of the pump. Does it go before or after the RPZ backflow? Anyone have any preferences as to brand or model; this one is an 8. First time in 45 years of doing this. Richard L.
